问题 modal auxiliaries

选项

答案Modal auxiliaries are special verbs which behave very differently from normal verbs. Here are a couple of differences: they don’t use an "-s" for the third person singular and are followed directly by the infinitive of another verb without "to". Basic modal auxiliaries in English include will, can, may, should, etc.
